在线调节加权因子的快时变系统自校正控制

Self-Tuning Control of Fast Time-Varying System with On-Line Adjusted Weighting Factor

在全系数自适应控制方法基础上,利用规范化模型方法,对快时变系统提出了一种自校正控制器,并在广义最小方差自校正控制律中引入了能自动整定的加权因子,以适应快速时变系统动态特性变化大的特点.数字仿真结果表明,这种控制器对快时变系统有很好的控制效果,而且控制器算法简单,对过程的非线性、阶次失配和未建模扰动均有较强的鲁棒性。

For fast time-varying system, based on the all - coefficient adaptive control method, presents a self-tuning controller by means of the normalized model method. The auto-regulation weighting factor is introduced into the generalized minimum variance self-tuning control law in order to fit in with the markedly changing dynamic characteristics of fast time-varying system. Digital simulation shows that the controller is satisfactory for fast time-varying system. The controller has simple algorithm and strong robustness for nonlinear, mismatched order and unmodeled disturbance of the process.
